Regression equations for each of eight regions are presented for determination of the 10-year flood. Peak flows for the 25- and 50-year floods can then be estimated from ratios developed for each region. Regression equations are not developed because of poor definitions for several areas that total about 20,000 square miles. The equations were based on multiple-regression techniques using annual peaks and basin characteristics for 303 gaged sites.</p>Dewatering of the Clayton Formation During Construction of the Walter F.

Well production in the high-yield area is mainly from the Newburg zone, a permeable stratum in the lower part of the Bass Island group. A structure contour map on the top of the Lockport Dolomite shows that the Newburg zone conforms to the configuration of the Cincinnati arch. The chemical quality of the water in the consolidated-rock aquifers is intimately related to the regional flow system, and undergoes a progressive change from a calcium bicarbonate-type in recharge areas to a calcium sulfate-type in areas of natural discharge.</p>Index to U.S. Geological Survey Computer Files Containing Daily Values for Water Parameters to September 30, 1971 -- Central Region2017-04-27T19:35:53-05:00https://digital.library.unt.edu/ark:/67531/metadc968054/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc968054/"><img alt="Index to U.S. Geological Survey Computer Files Containing Daily Values for Water Parameters to September 30, 1971 -- Central Region" title="Index to U.S. Geological Survey Computer Files Containing Daily Values for Water Parameters to September 30, 1971 -- Central Region" src="https://digital.library.unt.edu/ark:/67531/metadc968054/small/"/></a></p><p>Abstract: This report contains lists of stations at which the U.S. Geological Survey collects water data either on a continuous basis or at least on a daily basis.

The 6 to 22 years of stations were assembled and evaluated through use of computer techniques for data plotting and regression analysis developed by Steele (1972). Objectives of this evaluation were were (1) to show which parameters were highly correlative with the levels of specific conductance and(or) discharge and (2) to see if any changes in overall chemical character of the stream had occurred over the long term.</p>Effects of Ground-Water Development on the Proposed Palmetto Bend Dam and Reservoir in Southeast Texas2017-04-27T19:35:53-05:00https://digital.library.unt.edu/ark:/67531/metadc968131/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc968131/"><img alt="Effects of Ground-Water Development on the Proposed Palmetto Bend Dam and Reservoir in Southeast Texas" title="Effects of Ground-Water Development on the Proposed Palmetto Bend Dam and Reservoir in Southeast Texas" src="https://digital.library.unt.edu/ark:/67531/metadc968131/small/"/></a></p><p>Abstract: Ground water continues to discharge into the Navidad and Lavaca Rivers by seepage out-flow even though large amounts of ground water are pumped for irrigation. Although a reduction in streamflow probably has occurred, a complete loss of the low flow of the streams by infiltration to a lowered water table seems remote. The large ground-water withdrawals will continue to cause land-surface subsidence, which will range from 0.012 foot to more than 0.026 foot per year. A minimum of about 0.013 to 0.015 foot of annual subsidence at the upper ends of the proposed reservoir and a maximum of about 0.019 foot near the dam site can be expected. Structural failures of manmade features have not occurred from the subsidence, but regional changes in the land slope have occurred and will continue . Numerous fault traces have been mapped in the area, but most of the faults are inactive. If movement along the fault planes should occur, the vertical displacement probably will not exceed the total subsidence.</p>Effects of the Urbanization on Floods in the Houston, Texas Metropolitan Area2017-04-27T19:35:53-05:00https://digital.library.unt.edu/ark:/67531/metadc967944/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc967944/"><img alt="Effects of the Urbanization on Floods in the Houston, Texas Metropolitan Area" title="Effects of the Urbanization on Floods in the Houston, Texas Metropolitan Area" src="https://digital.library.unt.edu/ark:/67531/metadc967944/small/"/></a></p><p>Abstract: Rainfall and runoff data from drainage basins in the Houston metropolitan area and a 60-year rainfall record for the National Weather Service station, Houston-City, were used to simulate 60 annual flood peaks at 26 sites. Selected frequency characteristics, based on these simulated annual peaks are related to drainage area and percentage of impervious area. These relations which may be used to estimate the flood characteristics at ungaged sites, indicate that in the Houston metropolitan area, complete urbanization increases the magnitude of a 2-year flood nine times and increases the magnitude of a 50-year flood five times.</p>Geohydrology of the Cross-Florida Barge Canal Area with Special Reference to the Ocala Vicinity2017-04-27T19:35:53-05:00https://digital.library.unt.edu/ark:/67531/metadc967812/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc967812/"><img alt="Geohydrology of the Cross-Florida Barge Canal Area with Special Reference to the Ocala Vicinity" title="Geohydrology of the Cross-Florida Barge Canal Area with Special Reference to the Ocala Vicinity" src="https://digital.library.unt.edu/ark:/67531/metadc967812/small/"/></a></p><p>From preface: This report is concerned in general with the possible effects of the Cross-Florida Barge Canal on the pre-canal hydrologic regime of the area, and in particular with the effect of the canal on the natural levels, movement, and quality of the ground-water.</p>Salt-Water Movement in the Lower Withlacoochee-Cross-Florida Barge Canal Complex2017-04-27T19:35:53-05:00https://digital.library.unt.edu/ark:/67531/metadc968366/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc968366/"><img alt="Salt-Water Movement in the Lower Withlacoochee-Cross-Florida Barge Canal Complex" title="Salt-Water Movement in the Lower Withlacoochee-Cross-Florida Barge Canal Complex" src="https://digital.library.unt.edu/ark:/67531/metadc968366/small/"/></a></p><p>The intent of the investigation was to determine how salt water from the Gulf moves in the river-canal complex under the influence of various combinations of fresh-water discharge and ocean tide.

Recharge of ground or surface water of good quality has indicated, however, that injection through wells in an effective method of recharging the aquifer. Water that is slightly turbid can be successfully injected for a period of time, but generally results in constantly declining yields and capacity for recharge. Redevelopment through pumping and surging significantly prolongs the life of recharge wells under some conditions. Surface spreading is little practiced on the High Plains, but locally may be a feasible means of artificial recharge.</p>Stratigraphy and Geologic History of the Montana Group and Equivalent Rocks, Montana, Wyoming, and North and South Dakota2017-01-14T22:15:59-06:00https://digital.library.unt.edu/ark:/67531/metadc944642/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc944642/"><img alt="Stratigraphy and Geologic History of the Montana Group and Equivalent Rocks, Montana, Wyoming, and North and South Dakota" title="Stratigraphy and Geologic History of the Montana Group and Equivalent Rocks, Montana, Wyoming, and North and South Dakota" src="https://digital.library.unt.edu/ark:/67531/metadc944642/small/"/></a></p><p>From introduction: This is a progress report on regional stratigraphic and paleontologic studies of the Upper Cretaceous
